HOLDER OR HEAD FDR INCANDESCENT GAS-MANTLES- v No. 805,911.

Specification of Letters Patent.

Patented Nov. 28, 1905.

Application filed August e, 1903. Serial No. 16 8,444.

To a. whom, it may concern.-

Be it known that I, Hueo HEIDORN, a citizen 1 of the Empire of Germany,and a resident of Hamburg, in the Empire of Germany, have inventedcertain new and useful Improve: ments in Incandescent-MantleSupports,-of which the following is a specification.

This invention relates to supports for incandescent mantles, and has forits object to provide means for supporting an incandescent mantle, theuse of which insures an efiicient support of the mantle and prevents thesosupported mantle from being subjected to injurious strains-the causeof rapid deterioration and consequent uselessness. For this purpose theinvention consists of an incandescent-mantle support comprising amantlesupporting disk and means for clamping the. mantle to the same, aswill be more fully de scribed hereinafter and finally pointed out in theclaims.

In the accompanying drawings, which are on an enlarged scale, Figure 1is a plan of a mantle-supporting disk. Fig. 2 is a plan of aclamping-disk. Fig. 3 is a plan of a complete support or holder, andFig. 4 is a side View showing the mantlein dotted lines.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, a represents a flat ring or disk providedwith inwardly-projecting flexible teeth I) and having its top faceslightly curved inward or circularly inclined. On this disk or themantle e rests and is thereby supported, the object of the curved topface being to offer a smooth seat to the mantle to subject it to noprojections and to prevent thereby unequal strains. The flat ring ordisk 0, (shown in Fig. 2,) of somewhat smaller diameter than the diskor, is also slightly curved inward at its upper face and is providedwith an arched transverse connectin gpiece 0?, which is adapted to reston a forked or hook-shaped supporting-rod well known in the art, so notshown nor to be described in detail.

Having placed the'upper end of the mantle on the supporting-disk a, thesecond disk 0 is placed on top of the upper end of the mantle and disk aand the teeth or projections I) turned over, so as to press the disk 0against the supporting-disk a, and thereby clamp the mantle between thedisks and firmly secure and support the same.

The disks a and c, which are preferably of thin sheet metal, may be madeof any other durable fireproof material, as asbestos or such.

Various modifications may be usedwithout departing from the spirit of myinvention, the main object of the same being to provide means on whichthe mantle uniformly rests and to which it is securely attached.

My invention does away with the asbestos thread-holder, which is drawnthrough the top edge of the mantle and tied and which in the manufactureof the mantle necessarily increases its costs. Further disadvantages arethat when the mantle is exposed to vibrations independent of as well asdue to ignitions circles very readily appear immediately below the top,that in the course of use the curvature of the upper part of the mantlegradually becomes less and so the upper part of the mantle pointed,thereby decreasing the incandescence and lighting effect of the mantle,and that due to unequal strains arising from improp'er support thesides-of the mantle easily crack and frequently cause the breaking ofthe chimney, These disadvantages are obviated by my improved andherein-described means.

When packing mantles provided with my improved support in cardboardpackages, it is proposed, as the improved support is somewhat heavierthan the old asbestos threadsupport, to provide supports of paper,cardboard, or sheet-metal, or the like, conforming to the shape of themantle, and to push these under the pendant of the incandescentmantlethat is, under the transverse piece d and so keep the mantlesfirmly in position. v
